Abstract: The invention relates to a variable speed drive (1) intended to control an electrical load, said variable speed drive (1) being constructed to be inserted along a main axis (X) through an opening (200) produced in a frame (2). The variable speed drive has the particular feature of comprising an undercut (40) produced on its rear part and having a sufficient depth to allow its fixing plinth (111) to pass through said opening (200). The invention also relates to a system comprising the variable speed drive and a seal-tight architecture. The seal-tight architecture comprises said frame through which the opening (200) intended to accommodate the variable speed drive (1) is produced.

Abstract: The invention relates to a variable speed drive (1) connected upstream to an electric power grid (R) and downstream to an electric motor (M), the variable speed drive comprising notably a main casing comprising a base (14) and a main closure cover (15) closing on the base (14), a rectifier module (10), an inverter module (11), these modules being inserted inside the casing, and one or more bus capacitors (13). The main closure cover (15) comprises one or more openings (151) each traversed by a bus capacitor (13) and the variable speed drive comprises a secondary closure cover (17) fitting onto the main closure cover (15) and covering the said one or more bus capacitors (13).
